USGS Water-Year Summary 2022

07239700 NORTH CANADIAN RIVER NEAR YUKON, OK

LOCATION - Lat 35°32'22", long 97°44'32" referenced to North American Datum of 1927, in SW 1/4 SS 1/4 W 1/4 sec.04, T.12 N., R.5 W., Canadian County, OK, Hydrologic Unit 11100301, near left downstream end of bridge on new State Highway 4, 2.2 mi north of State Highway 66, 2.9 mi downstream from Shell Creek, and at mile 292.0.

DRAINAGE AREA - 13,456 mi² of which 3,497 mi² probably is noncontributing. From automated delineation using 10-meter National Elevation Dataset digital elevation model data dated 10/01/2006 and Watershed Boundary Dataset dated 10/01/2006, using Albers Equal-Area Projection, North American Datum 1983.

REVISIONS HISTORY - WSP 1341: Drainage area. WDR 2012: Drainage area.

SURFACE-WATER RECORDS

PERIOD OF RECORD - November 1943 to September 1999 (discharge measurements only), October 1999 to current year.

GAGE - Water-stage recorder. Datum of gage is 1247.66 ft above NAVD88.

REMARKS -

10/01/2021 - 9/30/2022: records fair.

Quality of data for other periods can be obtained by contacting the Oklahoma-Texas Water Science Center.

Some regulation by Fort Supply Lake (station 07236500) for period May 1942 to April 1948 and by Canton Lake (station 07238500) thereafter.

EXTREMES FOR PERIOD OF RECORD - Maximum discharge:, 25,100 ft³/s, August 21, 2007; Maximum gage-height 16.92 ft, August 21, 2007

WATER-QUALITY RECORDS

PERIOD OF RECORD -

WATER TEMPERATURE: November 1999 to current year.

SPECIFIC CONDUCTANCE: November 1999 to current year.

REMARKS -

Accuracy rating of the record for the 2022 Water Year:

WATER TEMPERATURE: Good; most of the data from this year could be rated as excellent; however, the rating has been downgraded to good because the sensor was not checked against a NIST-certified thermistor within this year.

SPECIFIC CONDUCTIVITY: Good; The required fouling corrections were generally small, with the exception of one large correction being required which led to data deletions. Calibration drift corrections of small magnitude were present as well as many data gaps.

Interruptions in record were due to malfunctions of the recording instrumentation or corrections to the data that exceeded allowable limits of correction. Additionally, some interruptions in data occurred due to the water levels dropping below the sonde during drought conditions.

Quality of data for other periods can be obtained by contacting the Oklahoma-Texas Water Science Center.
